People suffering from arthritic diseases are still relatively common in our daily life. There are many types of arthritis such as osteoarthritis, rheumatoid arthritis, crystalline arthritis, infectious arthritis, tuberculous arthritis, etc., but osteoarthritis accounts for the majority. Osteoarthritis can be treated in various ways such as medication, joint cavity perfusion, and surgery, depending mainly on the severity of the disease. Osteoarthritis often leads to the onset of pain, which is mainly due to inflammation and the physical irritation of friction in the joint itself. A straightforward and effective approach is to administer analgesic drugs orally. These are mainly anti-inflammatory and analgesic medications that are used. These drugs have a specific mechanism to reduce the inflammatory response while exerting an analgesic effect. They are used for therapeutic purposes. However, strong joint perfusion is also a therapeutic measure that flushes inflammatory material from the joint cavity. If the pain is acute and severe, an appropriate amount of glucocorticoids can be injected to effectively control the inflammation in the joint cavity. Sodium glutamate is also now commonly used for joint cavity injection therapy. This medication can help improve joint surface lubrication, reduce wear and tear due to arthritic injury, and reduce pain. As arthritic disease continues to progress, it may lead to joint deformity, intra-articular free bodies, uncontrollable synovitis in the joint, or even complete loss of joint motion. Surgical treatment is required depending on the severity of the state. In general, cases where there is still most of the joint preserved can be treated with arthroscopic surgery to clean up some irreversible diseased tissues and to clean and flush the joint, which helps to reduce pain and restore motor function. In cases where there is a greater degree of joint function loss, arthroplasty may be considered. This procedure is effective in restoring motor function to the joint. The treatment of arthritis depends largely on the stage of the disease and the degree of specific functional damage caused to the body. The appropriate treatment needs to be tailored to each case.
